Abstract

Free radicals in the gasphase of cigarette smoke were determined by spin trapping agent PBN (N-tert-butyl-2-phenyl nitrone) and DMPO (5,5-dimethyl-1-pyrroline-oxide) on electron spin resonance spectrometer. They were identified according to the spectrum parameters calculated from the spectra. The free radicals mainly consist of alkoxyl and alkyl free radicals, of which alkoxyl free radicals make up 60-70% of the total spectral components. These free radicals are very active and reactive. They can damage cells and lead to some diseases. This work points out the importance of scavenging the free radicals of cigarette smoke to prevent diseases caused by them.
